Strain energy harvesting performances of piezoelectric composite transducers in rolling tires: a numerical study

Arthur Givois, Florian Allein, Hung Le Khanh, Hervé Dietsch, Charles Croënne, Bertrand Dubus

<div><p>Tire-pavement contact is responsible for mechanical strain energy which can be used to power autonomous smart devices in the context of automotive industry. Power harvesting capabilities of piezoelectric composites included in the host structure are numerically evaluated from...

Terahertz time-domain ellipsometry with spintronic emitters: Pauli coefficients as a superior alternative to Jones and Mueller matrices

Pierre Koleják, Jiaming Liu, Robin Silber, Martin Mičica, Ondřej Ballada, Čestmír Barta, Romain Lebrun, Nicolas Tiercelin, Mathias Vanwolleghem, Kamil Postava

We introduce terahertz complete time-domain spectroscopic ellipsometry (THz-cTDSE), extending traditional ellipsometry by determining full Jones and Mueller matrices for in-depth material characterization. This marks the first application of spintronic terahertz emitters in ellipsometry, achieving...

Copper-decorated porous silicon for the bimodal detection of DMMP, a sarin simulant, by FT-IR spectroscopy and matrix-free laser desorption ionization mass spectrometry

Warda Raiah, Mohammed Guendouz, Parastesh Piratesh, Vincent Thomy, Joël Charrier, Yannick Coffinier

The release of organophosphates into the natural environment may directly and indirectly affect human health and cause severe damage to environmental ecosystems, thus raising global concern. In addition, some of these organophosphorus compounds (OPs) have been weaponized. Among them, Sarin, which...

Bi‐LORA : A Vision‐Language Approach for Synthetic Image Detection

Mamadou Keita, Wassim Hamidouche, Hessen Bougueffa Eutamene, Abdelmalik Taleb-Ahmed, David Camacho, Abdenour Hadid

Advancements in deep image synthesis techniques, such as generative adversarial networks (GANs) and diffusion models (DMs), have ushered in an era of generating highly realistic images. While this technological progress has captured significant interest, it has also raised concerns about the high...

In situ Investigation of 1T′/1H Phase Transition in Colloidal WS₂ Monolayers

Dario Mastrippolito, Ashkan Shahmanesh, Mariarosa Cavallo, Erwan Bossavit, Iman Laqchaa El Abed, Corentin Dabard, Shalini Singh, Mathieu Silly, Francesco Capitani, Nemanja Peric, Louis Biadala, Andrea Zitolo, José Avila, Francesco Carlà, Cesare Tresca, Emmanuel Lhuillier, Benoit Mahler, Debora Pierucci

Controlling the crystal phase of two-dimensional transition metal dichalcogenides (TMDs) is essential for tailoring their electronic and optical properties. Among the polymorphs of WS₂, the metastable 1T′ phase exhibits semimetallic or narrow-bandgap character and hosts quantum functionalities...
